PIPE OR HOSE CLEANING DEVICE.

lb al whom it may conce/rn:

Be it known that I, CHRISTIAN C. Guniiiannr, a citizen of the United States, residing at the city of New York, borough of Manhattan, in the county and State of New York, have invented certain new and useful improvements in Pipe or Hose Cleaning Devices, of which the following is a full, clear, and exact specification.

My invention relates to cleaning devices, and the saine has for its object more particularly to pro-vide a simple, etlicient and reliable device for cleaning hose, pipes, or other cylindrical structures.

Further, said invention has for its object lo provide a device which may be readily inserted into the pipe or other body to be cleaned, and thence be forced therethrough by means of a suitable fluid.

Further said invention has for its object to provide a cleaning device whereof the body portion is made of such size and weight that the same may be driven through a pipe with such force and speed that the resilient members arranged upon the surface of said body portion will be brought forcibly into engagement or contact with the inner surface or Wall of the pipe.

Further said invention has for its object to provide a cleaning device comprising a plurality of parts, which may be readily separated to facilitate cleaning or repairing the same, and which parts may be firmly secured together to form a unitary structure.

To the attainment of the aforesaid objects and ends, my invention consists in the novel details of construction, and in the combination, connection and arrangement of parts hereinafter more fully described, and then pointed out in the claims.

In the accompanying drawings forming part of this specification wherein like numerals of reference indicate like parts, Figure l is a side View showing a cleaning device constructed according to and embody- .ing my said invention, and Fig. 2 is a sectional view taken on the line 2-2 of Fig. l.

In said drawings o designates the device as a whole comprising a body-portion 6 composed of two semi-spherical sections 7, 8 having their edges rabbeted' and conformed to interlock with each other. In said semispherical sections 7, 8 are arranged series of Specification of Letters Patent.

radial apertures 9, 9 in which are secured by a wire l0 the ends of the tufts or bunches of bristles 1l ll. The tufts or bunches may be made of wire, bristles or any other suitable substance depending upon the particular purpose for which the device is to be used. The semi-spherical section 8 is provided with a centrally-located recessed aperture l2, and the semi-spherical section 7 is provided with a centrally-located threaded aperture 13, and l-L denotes a screw which extends through the aperture l2 in the section 8, and has its threaded end in engagement with the threaded aperture 13 in the section 7 in order to hold said parts united to form a single spherical structure having its entire outer surface covered with resilient members ll ll all of which project a uniform distance from the outer surface of said spherical body (S. By preference the semi-spherical sections 7, 8 are made of metal or other suitable material which is not affected by fluid, or subject to injury or distortion when in use.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

l. A cleaning device of the character described comprising a relatively heavy nonyielding spherical body composed of a plurality of parts conforming to each other and producing a continuousstructure, resilient members secured to said parts and extending outwardly therefrom and entirely covering said body, and means for securing said parts together, substantially as specified.

2. A cleaning device of the character described comprising a relatively heavy, hollow, spherical body composed of two semispherical sections having interlocking edges and provided with radial perforations, brushes secured in said perforations and entirely covering said spherical body, and a screw extending through said body for se- Patentetl Nov. 16, 1909.
